⟦tag:v2|task|2026-06-28-storyline-year-linking⟧ kind: task id: 2026-06-28-storyline-year-linking objective: 将剧情编辑器导出的年线正式接入任务系统主链，按 gameTime 推进，并在触发终局时中断后续章节。 scope: docs/handoff/**, docs/daily-plans/2026-06-28.md, src/data/storyEvents/**, src/data/eventTables/**, src/utils/storylineYearCompiler.ts, src/components/StoryTracking*.tsx acceptance:

• 至少一条年线能显示当前章节 / 下一章节
• 能按 dayWindow + timeAffinity + yearPhase 推进
• 遇到终局链时停止继续放出后续章节
• 不扩成通用剧情转换器 current state: verified blockers: none next action: none

summary:

• 编辑器导出源已正式接入年线主链，year tracking snapshot 已补齐，当前 acceptance 已收口。
• year2 缺章仅保留为后续 truth source，不再作为 28 收口 blocker。
